T0 at! w/tom it may concern:

Be it known that we, JOHN F. MEIGS, a citizen of the United States, and SIGARD A. S. HAMMAR, a subject of the King of Sweden and Norway, residing at Bethlehem, in the county of Northampton and State of Pennsylvania, have invented certain new and useful Improvements in Gun-Mounts, of which the following is a specification.

Our invention relates to gun-mounts; and it consists in making the parts, as fully set forth hereinafter, to simplify the construc tion and assembling and facilitate repairs, as Well as to protect the parts against injury, as fully set forth hereinafter and as illustrated in the accompanying drawings, in which Figure 1 is an elevation in part section of a gun-monut embodying our improvements. Fig. 2 is a plan of Fig. 1. Fig. 3 is a side view of the yoke-piece. Fig. 4 is a front view of the yoke-piece. Fig. 5 is a face view of part of the yoke-bracket. Fig. 6 is a face view of the cap-piece of the yoke-bracket. Fig. 7 is a section on the line 7 7, Fig. 1. Fig. 8 is an end view of the cradle, and Fig. 9 is a face View of the elevating rack-plate.

The pedestal A, which is approximately conical, is provided with a depending sleeve ac, terminating considerably above the baseline of the pedestal and adapted to receive the tapering pivot 1 of the yoke-piece B of the top carriage, and the yoke 2 is recessed to receive the bushings in which rock the trunnions 3 of the cradle O, in which rests the gun D. The pedestal and sleeve are recessed to receive annular bushings 4 5, to which are fitted bearings of the pivot 1, and a screwplug 6, fitting into the lower threaded end of the sleeve, supports the lower section 7 of a ball-bearing E, the balls running between said section and the upper section 8, on which rests the lower end of the pivot. This arrangement permits the yoke-piece B to be readily adjusted to its vertical position by turning the plug 6 from below, while as the bushings are cylindrical a proper bearing is secured in any position. A set-screw 10 secures the plug in any position to which it is turned. Oil 1s admitted to the lower bearing through a conduit 12 in the form of an inclined tube extending through the pedestal and through the bushing 5.

Upon the yoke-piece and itsattachments are carried the bearings for the elevating and traversing gear and the battery-boxes and adjuncts, and to reduce the cost of construction and facilitate repairs we connect the necessary parts detachably with the yoke-piece.

and with each other, as follows: A bracket F is bolted to the side of the yoke 2 at the rear of a sunken panel at, and a doWnwardextending arm 13 of this bracket has an inclined bore receiving a training-shaft 14, which operates through suitable gears-a Worm 15, that engages a training-rack 16, carried by the pedestalthe shaft being provided at the rear end with a hand-wheel 17. Forming part of the bracket F is the capplate G, bolted to the face of the bracket and the rearwardly-extended arm of which supports the shoulder-rest H. The bracket F and cap-piece G are recessed to form an intermediate gear-casing with bearings for the shaft 18, (dotted lines, Fig. 1,) carrying the bevel-gear 19 and worm-gear 20, the latter engaging a Worm-wheel 21 on a shaft 22 and the former a bevel-wheel 23 on a shaft 24, carrying the hand-wheel 25 at the outer end. The gears 1923 20 21 are within the casing, and the shafts 22 24 extend through bearings in the bracket and cap-plate. The parts may thus be readily assembled and the elevatinggearing fully protected. On the shaft 22 is a pinion 27, which engages the teeth of an elevating-rack 29, formed upon the rack-plate I, which is bolted to the side of the cradle near the rear end. To the outer face of the plate I is bolted a cap-plate 30, and the plate I and cap-plate are recessed to form an intermediate chamber y for the sight elevating gearing, (shown in dotted lines, Fig. 1,) with bearings for the operating-shaft 31. The battery-box J is supported in a bracket K, bolted to the outer face of the bracket F, and to the rear face 10 of the plate I, Fig. 9, is bolted one end of a shoulder-guard L, between which and the gun the flexible electric conductor 38 hangs, guided by eyes 39 40 41 to the firing devices at the breech of the gun. The conductor is thus supported in a loop to afford the slack required on the recoil, but so guarded and covered by the shoulder-guard that it cannot catch with anything in the manipulation of the gun.

In one piece with the cradle and below the same is the cylinder or case 49 for the recoil mechanism, springs, or pistons.

Without limiting ourselves to the precise constructions shown, we claim- 1. In a gun-mount, the combination of a pedestal having a depending sleeve, cylindrical bushings therein, an elevating-plug adapted to screw into the lower end of said i said plug, substantially as set forth.

sleeve, and a yoke-piece having a pivot adapted to said bushings and supported by 1 2. In a gun-mount, the combination of a pedestal having an internal depending sleeve, cylindrical bushings therein, an elevatingplug screwing into the lower end of said sleeve, a yoke-piece having a pivot adapted to said bushings and supported by said plug,

devices, said devices comprising a shaft ex-v cradle, a plate carrying tending transversely of said bracket and plate and engaging with a shaft located between said bracket and plate and extending parallel thereto, substantially as set forth.

5. The combination in a top carriage, of a yoke-piece, a bracket secured thereto, a caplate, and means for securing it to the bracket, the bracket and capate recessed to receive the elevating-gear and to constitute bearings for the shafts thereof, substantially as set forth. 6. The combination of the yokepiece, an elevating rack and a detachable bracket carrying incased elevatinggearing ponrlilected to the yoke, substantially as set ort connected to the cradle,

7. The combination with the yokepiece,.

of arack-plate I ,having arack 29 and recess y, and a cap-plate 3O recessed and covering the recess y to form a gear-chamber for the sightelevating gear, substantially as set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
